Information System Security

In Biometric Authentication, overly exact match will cause more secure authentication.

System performs a N:N comparison against a biometric DB in attempt to establish the identity of an unknown individual.

Which option is not related to voice recognamtion?

In biometric functionality, Which step is before Application Device step?

____________ means; probability that the system fails to detect a match between the input pattern and a matching template in the database.

In 7 factors for biometric authentication, which one explain:
biometric features that remain constant over time

In 7 factors for biometric authentication, which one explain:
accuracy, speed and robustness of technology

What is the most common type of biometrics device in the enterprise?

Correspondingly, a higher threshold will reduce the ______ but increase the _______.

Which option is not a security violation for false acceptance?

Biometric authentication base on something you _____

A biometric modality that uses the cadence of an individual's typing pattern for recognition.

Which option is not biometric method thet you are?

It measures the percent of invalid inputs which are incorrectly accepted.

For checking message integrity, destination checks provided hash code from source with public key of source.

In certificate verification, Consumer must have a trusted copy of the subject’s public key. The consumer can then chain from his trusted copy of subject’s public key to a trusted copy of issuer’s public key.

Two messages can have same hash value.

In Digital Certificate, the plaintext contains of:
Issuer (CA)
Subject (user)
Subject (user) Public key
Expiration date

If the threshold is reduced, there will be fewer false false accepts but more non-matches.

In hash code, a small change in the input (message) drastically changes the output (digest).

The matching algorithm performs a decision based on a threshold which determines how close to a template the input needs to be for it to be considered a match.

The system will succeed in identifying the individual if the comparison of the sample to a template in the DB falls within a previously set ___________.

_________ means; when subject is trying to fool the system.

The other term for False Accept Rate is _____________.

For creating a digital signature, the process as follow:
Message --> Hash code --> encrypt hash code with Source private key
